How to
estimate your IQ based on your GRE or SAT scores

New and improved method to estimate
your IQ based on your GRE scores:

1. Add up your Verbal + Quantitative scores.
2. Look at the table given below.
It also gives your percentile with respect to the general population. An example of a test with 15 IQ points per standard deviation (SD) is the Wechsler. An example of a 16 SD test is the Stanford-Binet.

This way of estimating was based simply on an
interpolation between two points: 1) the theoretical average IQ of GRE takers=
115* with the average
GRE V+Q score being 1035 in 1999-2000, and 2) the minimum IQ level of
the Ultranet society= 164 with the accepted (old) GRE score being 1610. The resulting
formula was IQ=26.8+0.085*GRE. The formula corresponded serendipitously
well with existing critera. For example, the Triple
Nine Society and IQuadrivium,
both 99.9th percentile societies, accept GRE scores of 1460 or 1454 and
IQ scores of 149 or 150. Intertel and the Top One Percent
Society ask for IQs of 136 or 137 and a GRE score of 1300. Mensa asks for an IQ of 132 and asked for a V+Q score of 1250. You can see below
how close the table came to these values (1.3 IQ points or less).
The IQs referred to are on the 16 SD scale. I don't know if the IQ values
much below 115 are as accurate or not.

To estimate your IQ based on your SAT scores:

Note: The first two links are based on my formulae and the last two links are from published sources.

If you took the SAT I, go to this page.
If you took your SAT before April 1995 and your score was higher than 1280, go to this page otherwise go here.
If you took the SAT many decades ago, go to this page.

Note: Mensa considers that scores from after January 31, 1994, "No longer correlate with an IQ test."
